I'm looking for way to make sure the files I deploy to Google AppEngine (Python) using gcloud app deploy are only the files I need.
In the log file it only list files that are skipped but not the files that are deployed.
Is there a way to see this list?
All the files and directories present or sym-linked under an app service/module directory (i.e. the directory where the respective service/module's .yaml file exists) will be deployed when the respective app service/module is deployed, unless they're skipped files (i.e. they match the default or configured skip_files patterns - see the skip_files row in the app.yaml Syntax doc table).
So you can obtain a recursive listing of your service/module directory (make sure you follow/include sym-linked sub-directories), then drop the skipped files from it.
Alternatively, if you are using appcfg.py update for deployment, you can use its --noisy option which will make it display, among other stuff, that desired info, like this:
...

Unfortunately I don't see a similar option for gcloud app deploy.
EDIT:
As of Google Cloud SDK 171.0.0 adding the option --verbosity=info provides you with processed files in a log line after it finishes uploading the files
